The Rome that we see today is built on the ruins of one of the largest empires of the ancient world that now sleeps beneath the paved streets and highways. Discover the secrets and mysteries of this civilization by embarking on a tour of the Sotterranei Di Roma (Underground Rome). The well-preserved archeological site explores the foundations of the city, hydraulic systems, caves, tunnels and labyrinths. In-depth exploration is open to the members of the Centro Ricerche Speleo Archeologiche while guests can register for guided tours which are organized regularly. Visit the website for more details.
